Abstract

In order to compare individuals in basal metabolism, the usual procedure is to express the rate in kilocalorie per square meter of surface area per hour. The reason for this is that body heat loss, and hence heat production, is more closely related to body surface area than to body weight. On the other hand, the oxygen utilization (VO2) or energy expenditure during exercise is generally adjusted for body weight and expressed in milliliters of oxygen per kilogram body weight per minute. In this case, the assumption is made that most of the energy expenditure is a result of moving the weight of the body. We raised the question whether it is better to adjust for body weight or surface area, even at the lowest work loads. Oxygen uptake measurements had been collected on 1,001 males, age 10-54, while they walked at 80.6 m/min at a variety of grades and analysis of these data may provide answers to the questions posed.
